6 Claims.

This invention relates to braces or supports for shaker co-nveyers and has for its primary object the provision of a device of this character which may be readily set up and adjusted to a ceiling and flooring of a mine and which will efl'iciently maintain a conveyer in proper position and permit raising and lowering of said conveyer and the leveling thereof where the mine floor is uneven.

With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed. J

For a complete understanding of myinvention, reference is to be had to the following description and accompanying drawing, in which:

Figure l is a top plan view illustrating a brace constructed in accordance with the present invention and having associated therewith a shakerconveyer.

Figure 2 is a sectionalview taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken on the. line 3-3 of Figure 2.

Referring in detail to the drawing, the numeral l indicates a fragmentary portion of a shaker conveyer trough section having secured to opposite sides thereof channeled members 2, which members are connected together by a brace 3, secured to and extending beneath said trough section.

Arranged at opposite sides of the conveyer l are vertically arranged supporting members or jacks 4 adapted to be interposed and secured between a mine roof and bottom in a usual manner.

Each of said jacks is constructed of telescopic sections. 5 and 6. The section 5 is free to slide within the section 5 but is held against rotation relative to the section 6 by a pin 1 fitting in a groove 8 thereof. A base 9 is'formed on the section 5 and a head H1 is formed on the section 5. The base 9 is adapted to rest on the flooring of a mine while the head In is adapted to be adjusted into engagement with the ceiling of a mine. Feed threads I! and H are formed on the sections 5 and 6. Journaledon the upper end of the section 6, and meshing with the feed threads II, is a feed nut 13 having a hand wheel II. By

rotating the hand wheel l4 in opposite directions, 1

the section 5 can be adjusted inwardly and outwardly of the section 6. A feed nut I5 meshes with the feed threads l2 of the section 6 and is provided with a hand wheel 16. v

The feed nuts I5 have grooves to receive split (01. nae-220) clamps I! which form supporting collars for stub shafts 29]. The feednuts. 15 are free torotate in the clamps I1 and formed on the latter are apertured extensions I8 to receive pivot pins l 9. The pivot pins 19 are carried by said stub shafts and said stub shafts are connected together by a brace 25 extending under the conveyer. The stub shafts have journaled thereon rollers 22 which engage in the channeled members 2. The pivot pins 19 have heads andslots, the latter receiving removable pins 23 secured to the stub shafts by flexible elements 24.

The brace 2| thus rigidly connects the rollers 22, 22 and stub shafts '20, 2B in oppositely disposed pairs andsince said stub shafts are pivotally connected to the clamps l'l', I l-Lindependent vertical adjustment of said clamps may adjust the trough l' to the desired position with respect to the ground or rest of the trough line, and permit the trough line to readily conform to an uneven mine bottom. Likewise the trough section may be vertically adjusted and held in such adjustment when the jacks 4 are disposed at various angular relationships with respect to each other.

A device of the character described maybe readily set up within an entry or working place of a mine by adjusting the sections 5 and Ii're'lative to each other to bring the'bases and. heads engagement with the floor and ceiling of the mine. This adjustment is easily accomplished by the rotation of the hand wheels I4. The supporting members 4, thus arranged, effectively support the conveyor, the latter capable of having relative movement thereto by the rollers 22, engaging the channeled members, and said rollers besides serving as a' support for the trough, likewise tend to hold the trough from lifting movement and also hold it in horizontal alignment I with the rest of the conveyor, serving'as a'guide frame therefor. Further, the conveyer maybe leveled by adjusting the feed nuts IE on the section 5 either in an upward or downward direction. The stub shafts 20 may be readily detached from the feed nuts l5 when it is desired to remove the conveyer from the support and'move the support to another place in the mine.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be construed as limiting my invention to the specific embodiment illustratedexcepting as it maybe limited in the appended claims.

rocable movement with respect thereto including a pair of oppositely disposed rollers, supporting and guide members extending along opposite sides of said conveyor trough adapted to engage said rollers, and a supporting connection between i said rollers and jacks including support members mounted on said jacks for vertical adjustment with respect thereto,, a pair of oppositely dis-.

posed stub shafts having 's'aid'rollers journaled thereon, and pivotal connections between said stub shafts and support members, permitting said stub shafts to be horizontally positioned, when said jacks arein various angular positions with respect to each other and permitting said shafts and rollers to be adjusted to level said trough in a transverse direction and permit said trough to be alignedflwith the remainder of the conveyor trough line in a longitudinal direction.

2. In a shakerconyeyertrough support, a pair of spaced apart supporting jacks adapted to be interposed between a mine roof and floor, a pair of spaced apart shafts ha ving rollers thereon adapted .to form a slidable support for a trough of a shaker conveyor trough line, a member extending beneath said trough, for rigidlyconnecting said shafts together, support members mounted on said jacks for vertical adjustable movement therealong, and pivotal connections between saidsupport members and shafts to permit independent vertical adjustment of said shafts andto permit a plurality of sets of said supporting jacks and rollers to be readily adjusted rto supportfa shaker conveyer trough line in aligned relationship in both horizontal and verticalplanesand level in a transverse direction where the floor is uneven and saidjacks are secured between: the mine roof and floor in various angular'positions with respect to each other.

3, In a shaker conveyer trough support, a pair of spaced apartsupporting jacks adapted to be interposed between a mine roof and floor, a pair of spaced apart shafts having rollers thereon adapted to form a support for a trough of a shaker conveyer trough line, support members mounted on saidjacks for vertical adjustable movement therealong, pivotal connections between said support members and shafts to permit said shafts and rollers to be horizontally positioned when said jacks extendin various angular positions with respect to the ground, and self-contained means for independentlyivertically adjusting said support members along said jacks, to level said trough in a transverse direction and align said trough with the rest of the trough line in a longitudinal direction.

4. In a shaker conveyor trough support, a pair of spaced apart supporting jacks adapted to be interposed and secured between a mine roof and floor, a conveyor trough adapted to be supported to reciprocate betweensaid jacks, supporting and guide members extending along opposite sides of said conveyer trough, rollers engaging said guide members for supporting said trough, a pair of oppositely disposed stub shafts upon which said rollers are journaled, means for rigidly connecting said stub shafts in oppositely disposed pairs, support members mounted on said jacks for vertical adjustment therealong, andpivotal connections between said stub shafts and support members, permitting independent adjustment of 3 said stub shafts along said jacks, when said jacks are in various angular positions with respect, to

,each other, and permitting said shafts and rollers to be readily adjusted to support said trough ,in a level position in a transverse direction and in aligned relationship-"with the rest of the conveyer. I

5. In a shaker conveyer trough support, a pair of spaced apart supporting jacks adapted to be interposed between a mine roof and floor, aconveyer trough adapted to be supported to reciprocate between said jacks, supporting and guide members extending along opposite sides of said conveyer trough, rollers engaging said guide members for supporting said trough, a pair of oppositely disposed stub shafts upon which said rollers are journaled, means for rigidly connecting said stub shafts in oppositely disposed pairs, support members mounted on said jacks for vertical adjustment with respect thereto, pivotal connections between said stub shafts and support members permitting independent adjustment of said stub shafts along said jacks, when said jacks are in various angular positions with respect to each other, and self-contained means for vertically movingv said support members along. said jacks to permit ready adjustment of said stub shafts along said jacks and permit a plurality of sets of said jacks and shafts and rollers to support a trough line ina level position in a transverse direction and in aligned relationship in a longitudinaldirection.
